. To all whom it may concern:

Be it known that 1, DAVID F. DRAPER, a citizen of the United States, residing at Georgetown, in the county of Williamson and State of Texas, have inventedcertai'n new and useful Improvements in Metallic Roofs, of which the following is a specification.

This invention relates to roofs and more specifically to portable metallic roofs.

The object of my'invention is to provide a roof which will be simple and economical in construction, in that it does not require the services of a skilled mechanic to apply the roofing; the various parts may be shaped in shop or factory, after which they may be removed to the building under construction and placed in position without the need for soldering tools or additional fitting of any kind. Therefore, when used on a farm building or at some other remote place, the builder is saved the expense of a sheet metal worker to put on the roof.

Another object of my invention is to provide a roofing which will avoid the necessity for the sheathing commonly nailed to the rafters of a building and to which ordinary roofing is secured.

A further ob'ect of my invention is to provide a portable roof which may be set up by contractors on temporary buildings and sheds, and which may be knocked down for further use. Furthermore, while primarily intended for use upon the roof of a building, my forms of-roofing are also applicable to the walls of a building, wherein the cost of sheathing and weather-boarding is saved, as well as the cost of labor in applying such materials.

A still further object of my invention is to provide an absolutely fire-proof building at. a very small cost, as nails are not absolutely necessary in applying the roofing, and it ma be laid upon an all metal framework.

(d ther objects of this invention not at this time more particularly enumerated,will be clearly understood from the detailed description and drawings forming a part of this specification.

Furthermore, thls invention consists 1nthe novel arrangement and combination of parts more particularly described in the following specification and embodied in the claims appended hereunto and forming a part of this application. I q

Referring now to the drawings, which are merely illustrative of my invention:

Figure 1 is a sectional view of my roofing assembled.

Fig. 2 is a fragmental perspective view with one of the'caps removed.

Referring further to the drawings, wherein similar reference characters designate similar parts throughout the respective views 1 designates the body portion of a sheet metal cover plate, having an angular flange 2 along one end adapted to engage the ridge-pole 4 of a roof, and an oppositely .turned flange 3 on each side of and at right angles to said body portion. Said body'portion is of a width adapted to fit between the rafters of a building,while the flanges 3 lieflat against the side of said rafters. In

a ridge-roof construction, one of the flanges.

2 engages the ridge-pole 4 on one side of the roof, while the body portion 1 of the cover plate extends downwardly between therafters upon the other side of the roof. The oppositely disposed cover plate has its flange 2 overlap the body portion 1 of the first-. laid cover plate, at a point along the ridgepole of the roof.

A cap member shown in Fig. 2 shows two interfitting members, each having a top portion 13, a depending side wall 1 1 integral with and at right angles thereto, and a flange 15 integral with said side wall and at right angles thereto. In this construction, the width of the rafter may vary within certain limits, as the'roof portions of the cap member overlap to fit upon the top of the rafter, and so that the side walls will cover the upwardly extending flanges 3 of the.

cover plates, and that the flanges 15 thereof will extend for a certain distance upon the body portion of said cover plates. Perforations 16 are provided through the walls 1 1 of said interfitting members adapted to receive securing elements for fastening the cap members to the rafters of a roof.

The utility, adaptability, and advantages of my improved form of roof construction 7 being obviously apparent, it is unnecessary to further enlarge upon the same herein.

Having now described and pointed out the new and useful features of my invention,

I do not limit myself to the shape of certain parts where the shape is not essential, nor do I restrict myself to the exact details of con- 4 struction shown and described, but mean and intend to claim all equivalents and variations thereof not departing in principle from my invention and falling within the purview of the appended claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a ridge roof construction, the combination with a ridge-pole, rafters, and roof plates having flanges along the sides of the rafters, of retaining means therefor comprising a pair of cover sections having the marginal edges formed with oppositely and laterally extending rafter and roof flanges,

said sections having the rafter flanges thereof arranged in over-lapping relation on the rafters and the body portions thereof engaging the flanges of the roof plates.

2. In a ridge roof construction, the combination with a ridge pole, rafters, and roof plates having flanges along the sides of the rafters, with a pair of interfitting cover plates comprising, a sheet of metal having the top and bottom marginal edges thereof bent at right angles in opposite directions to the body portion, the upper marginal edges being adapted to engage each other in adjusting overlapping relation providing means for accommodating the cover members to rafters of different widths, the bottom marginal edge extending over the edges of the roof plates, the body portion of said cover plates being provided with openings, said openings providing fastening' means for the cover members to the rafters. I

In testimony whereof, I affix my signature in presence of two witnesses.
